Abstract

Hepatic mesenchymal hamartoma is a rare benign tumor.
We present an unusual case of a fetal abdominal cyst, later
diagnosed histopathologically to be mesenchymal hamartoma of
liver. The organ of origin was indeterminate on both prenatal and
postnatal ultrasounds. As there are no specific sonological
findings, whenever a large multicystic fetal abdominal cyst is
seen, mesenchymal hamartoma should be considered as a possibility.
